â– Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching and leaning reduce the effectiveness of the
belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat belts. Devices intended to improve comfort
or reposition the shoulder part of a seat belt can reduce the protective capability
and increase the chance of serious injury in a crash.
Your vehicle monitors front seat belt use. If
the power mode is set to ON before the
driver’s seat belt is fastened, the beeper will
sound and the indicator will blink. If the driver
does not fasten the belt before the beeper
stops, the indicator will remain on.
The beeper will also periodically sound and
the indicator will blink while driving until the
driver’s and front passenger’s seat belts are
fastened.â– 
Seat Belt Reminder
1About Your Seat Belts
If a rear seat passenger moves around and extends
the seat belt, the lockable retractor may activate. If
this happens, release the retractor by unfastening the
seat belt and allow the belt to retract completely.
Then refasten the belt.1 Seat Belt Reminder
The indicator will also come on if a front passenger
does not fasten their seat be lt within six seconds after
the power mode is set to ON.
When no one is sitting in the front passenger’s seat,
the indicator will not come on and the beeper will not
sound.
The indicator also may not come on and the beeper
may not sound when the occupant is not heavy
enough to trigger the weight sensor. Such occupants
(e.g., infants and smaller children) should be moved
to the rear seat as a depl oying front airbag likely will
injure or kill them. 2 Protecting Child Passengers P. 54

The front seats are equipped with automatic
seat belt tensioners to enhance safety.
The tensioners automatically tighten the front
seat belts during a moderate-to-severe frontal
collision, sometimes even if the collision is not
severe enough to inflate the front airbags or
the driver’s knee airbag.
Are the motor-powered pretensioners that
start to retract the front seat belts when the
CMBS
TM, brake assist system, or VSA ® system
is in operation. They may also activate when
you steer the vehicle hard, or the vehicle is
impacted. After retracted, the seat belts are
slackened to their original positions.
As convenient features, the e-pretensioners
slightly retract the seat belts when you latch
the seat belt buckle, depress the brake pedal
more aggressively than you normally do, or
make a sharp turn, and fully retract when you
release the seat belt buckle.

thoroughly inspect the seat belt system as it may not
offer protection in a subsequent crash.
During a moderate-to-severe side impact, the
tensioner on that side of the vehicle also activates.

Airbags can pose serious hazards. To do their job, airbags must inflate with
tremendous force. So, while airbags help save lives, they can cause burns, bruises,
and other minor injuries, sometimes even fatal ones if occupants are not wearing
their seat belts properly and sitting correctly.
What you should do: Always wear your seat belt properly, and sit upright and as
far back from the steering wheel as possible while allowing full control of the
vehicle. A front passenger should move their seat as far back from the dashboard as
possible.
Remember, however, that no safety system can prevent all injuries or deaths that
can occur in a severe crash, even when seat belts are properly worn and the airbags
deploy.
Do not place hard or sharp objects between yourself and a front airbag.
Carrying hard or sharp objects on your lap, or driving with a pipe or other sharp
object in your mouth, can result in injuries if your front airbag inflates.
Do not attach or place objects on the front and driver’s knee airbag covers.
Objects on the covers marked SRS AIRBAG could interfere with the proper
operation of the airbags or be propelled inside the vehicle and hurt someone if the
airbags inflate.â– 
Important Facts About Your Airbags
1 Important Facts About Your Airbags
Do not attempt to deactivate your airbags. Together,
airbags and seat belts provide the best protection.
When driving, keep hands and arms out of the
deployment path of the front airbag by holding each
side of the steering wheel. Do not cross an arm over
the airbag cover.

uuAirbags uTypes of Airbags
Safe Driving
Types of AirbagsYour vehicle is equipped with four types of airbags:
• Front airbags: Airbags in front of the driver’s and front passenger’s seats.
• Driver’s knee airbag: Airbag under the steering column.
• Side airbags: Airbags in the driver’s and front passenger’s seat-backs.
• Side curtain airbags: Airbags above the side windows.
Each is discussed in the following pages.Front Airbags (SRS)The front SRS airbags inflate in a moderate-to-severe frontal collision to help protect
the head and chest of the driver and/or front passenger.
SRS (Supplemental Restraint System) indicates that the airbags are designed to
supplement seat belts, not replace them. Seat belts are the occupant’s primary
restraint system.
The front airbags are housed in the center of the steering wheel for the driver, and
in the dashboard for the front passenger. Both airbags are marked SRS AIRBAG.â– 
Housing Locations
1Types of Airbags
The airbags can inflate whenever the power mode is
in ON.
After an airbag inflates in a crash, you may see a
small amount of smoke. This is from the combustion
process of the inflator ma terial and is not harmful.
People with respiratory problems may experience
some temporary discomfort. If this occurs, get out of
the vehicle as soon as it is safe to do so.1 Front Airbags (SRS)
Dual-Stage, Multiple-Threshold Front Airbags
(SRS)
Your vehicle is equipped with dual-stage, multiple-
threshold front airbags (SRS).
During a frontal crash severe enough to cause one or
both front airbags to deploy, the airbags can inflate
at different rates, depending on the severity of the
crash, whether or not the seat belts are latched, and/
or other factors. Frontal airbags are designed to
supplement the seat belts to help reduce the
likelihood of head and chest injuries in frontal
crashes.

uuAirbags uFront Airbags (SRS)
Safe Driving
Front airbags are designed to inflate during moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won’t interfere with the driver’s visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until they see them lying in front of them.â– 
Operation

How the Front Airbags Work
1 How the Front Airbags Work
Although the driver’s and front passenger’s airbags
normally inflate within a split second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protection, and the supplemental
protection offered by the airbag would be minimal.

44
uuAirbags uFront Airbags (SRS)
Safe Driving
â– When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scrapes, or even broken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passen ger to move toward the front of the vehicle. Side
airbags and side curtain airbags have been specifically designed to help reduce the
severity of injuries that can occur during a moderate-to-severe side impact which
can cause the driver or passenger to mov e toward the side of the vehicle.
Rear impacts: Head restraints and seat belts are your best protection during a rear
impact. Front airbags cannot provide any significant protection and are not designed
to deploy in such collisions.
Rollovers: Seat belts, and in vehicles equipped with a rollover sensor, side airbags,
and side curtain airbags offer the best protection in a rollover. Because front airbags
could provide little if any protection, they are not designed to deploy during a
rollover.â– When front airbags deploy with little or no visible damage
Because the airbag system senses su dden deceleration, a strong impact to the
vehicle framework or suspension might cause one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in the vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.â– When front airbags may not deploy, eve n though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

uuAirbags uFront Airbags (SRS)
Safe Driving
Your front airbags have advanced features to help reduce the likelihood of airbag
related injuries to smaller occupants.
The driver’s advanced front airbag system
includes a seat position sensor.
If the seat is too far forward, the airbag
inflates with less force, regardless of the
severity of the impact.
The passenger’s advanced front airbag system
has weight sensors.
Although we recommend against carrying an
infant or small child in front, if the sensors
detect the weight of a child (up to about 65
lbs or 29 kg), the system will automatically
turn off the passenger’s front airbag.■
Advanced Airbags
1Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator will come on and the airbag
will inflate with full (nor mal) force, regardless of the
driver’s seating position.
For both advanced front airbags to work properly:•Do not spill any liquid on or under the seats.•Do not put any object under the passenger’s seat.•Make sure any objects are positioned properly on
the floor. Improperly positioned objects can
interfere with the advanced airbag sensors.•All occupants should sit upright and wear their seat
belts properly.•Do not place any cover over the passenger side
dashboard.
Make sure the floor mat behind the front passenger’s
seat is hooked to the floor mat anchor. An improperly
placed mat can interfere with the advanced airbag
sensors. 2 Floor Mats P. 437
